Letters Patent No. 85,7 36, dated .Tamm/ry 12, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom 'it l:m1/y concern:

` Be it known that I, IsArAH B. GILBERT, of Lewisville, in the county of Henry, and State of Indiana, have invented a new and useful Improvement in Oultivators; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, snfcient to enable others skilled in the art to which the invention appertains, to fully understand and use the same, reference being had tothe accompanying drawings, which are made a part this specification.

The subject of this invention is a cultivator in which provision is ,made for turning the tongue to the right or left by `means of a lever pivoted to its rear end, to 'be moved by hand,thereby enabling the implement to be more readily turned at the ends of rows and at points where stumps or other obstructions are to be avoided; and the shovel-carriers are pivoted in such a manner that they may move vertically or laterally, and they are employed in connection with devices which enable them Y' to be raised independently or allI together, as occasion may require.

'In the drawings- Figure 1 is a plan of a cultivatorillustrating my invention.

Figure 2 is a vertical section in the plane indicated by the line a: as, fig. 1.

-Figure 3 is a rear view of a portion of the cultivator, illustrating the parts whereby the shovels are raised.

Similar letters of reference indicate corresponding parts in the several figures.

'Ihe frame of this implement comprises the main cross-beam A and the uprights B B, joined to each end thereof.

The uprights B B are' provided, near their lower ends, with the journals for the ground or carryingwheels c c.

In iig. l, one-half ofthe beam A is broken away,'to expose parts below, but the entire beam is exhibited in iig. 3.

The frame also includes two vertical bars D D, at ont, joined by a transverse bar, E, these last-mentioned parts being connected with the parts A B B by the rods F. A

Rods G, extending rearward from the uprights B B, support the drivers seat, H.

`I represents a transverseshaft, supported beneath the main beam A by the-braces J J, which` connect the uprights B B with said beam.

K is an arm, projecting backward from the shaft I to a point sufficiently near the drivers seat to enable the driver to depress the same by hand or foot, for a purpose to be explained.

L L are the bars which carry the shovels or blades L', which penetrate the soil.

Two lof the shovel-carriers L L are attached to each of the forward uprights D D by the metallic box or bearing-plate M, which bearings are made fast to said uprights in any suitable manner.

Each\shovelcarrier L is attached to the bearingplate M through the medium of the horizontal pivots m, 'lugs m1, and vertical pivots fm2. The pivots m adapt the shovel-carriers to be raised and lowered, and the ...f/YM/ 4 pivots fm. enable said shovel-carriers to be moved laterally.

The shovel-carriers are supported, at a point somewhat forward of their mid-length, by links or hangers N. (See rear view, iig. 3.)

The hangers are suspended from the forwardends of bent levers O, which have their fulcra upon the shaft I.

I' is a rod or bar made fast at its ends to the shaft'I.

rIhe levers O,- projecting backward as well as forward of the shaft I, are turned by the depression ofthe arm K. rlhe rod I' bears downward upon the levers O, behind their fulcra, and thus all the shovel-carriers, with their shovels, may bev raised at once. Each shovelcarrier may, however, -be raised independently of the others by means of its leverO.

By means ofthe notched bar S, secured to the beam A, the arm K maybe adjusted vertically, so as to regulate the depth of the shovels penetration.

In iig. 1, the rear portion of the lever Q is represented 'as broken away, so as to exhibit the arm K,

which is beneath.

The above-described devices place the cultivatorshovels or teeth under the complete control of the operator. Ihey are simple in arrangement, and. can be managed with facility.I

The tongue I has pivotal attachment, at e, to the bar E, and upon its rear end -is formed a tenon or tongue, p,`which, being confined in a slot or groove, a, in the front side of beam A, serves to guide the rear end of the tongue under its lateral movement.

This movement is eiiected by means of a lever, Q,- which is pivoted upon the beam A, and which has a pin, q, upon the forward end, occupying a slot or opening ip the rear end of the tongue P. By means ofthe lever'Q lthe driver can turn the tongue to any desired angle with the beam A, and hence the implement may be turned short round, so as to vavoid stumps, 85e., or when the end of the row is reached.

The whflie-trees fl 'I are attached to a chain, T,' running over pulleys, so asY to equalize the draught; but, if preferred, they may be attached in any other suitable manner, and in a higher position than that in which they are represented.

Having thus described my invention,

What I claim. as new herein, and desire to secure by Letters Patent, is-

l. The transverse shaft Il and rod I', in combination with the arm K and levers O, for raising the shovelcarriers separately orcollectively, substantially as described.

2. rIhe combination of the beams L L', plates M, pivots m m2,' lugs m1, shaft I, arm K, rod I', levers O, pivoted tongue P, and lever Q, substantially as described, for the purpose specied.

To the above I have signed my name, this 31st day of July, 1868.
